The Flutter In Pinhole by Yoo Geun-hyuk & Yoon Bo-jung is a no frills cardboard camera with an interesting concept behind it. It works just like a pinhole camera, but the cool part is that each one comes setup so that you can take the photo you shot and send it to a penpal in another country using the postcard adorned to the camera. And once your camera is all used up, you can easily discard the part of the camera that you don’t repurpose by simply putting it in with your paper recyclables.
